Gel permeation chromatography--multi-angle laser light scattering characterization of the molecular mass distribution of 'Pronova' sodium alginate.

510 Conclusions We have shown evidence for the bridging flocculation of PSL by p-LG. The change in surface charge of the PSL spheres resulting from adsorption of p-LG molecules correlates with the formation of aggregates bridged by protein molecules. To develop models of the kinetics of bridging flocculation, some measurements of aggregation as a function of time and temperature have been carried out and will be reported elsewhere. Future work will aim to describe the kinetics of aggregation quantitatively and the diffusion of PSL in more highly aggregated (pre-gel) and gelled whey protein systems will be investigated using P.C.S. and forced Rayleigh scattering.
